Tests fail if RPS server isn't localhost

To Reproduce 🪜
Steps to reproduce the behavior:

Change the environment to use a remote RPS server, for example:

diff --git a/src/environments/environment.ts b/src/environments/environment.ts
index 63d436c..7904a38 100644
--- a/src/environments/environment.ts
+++ b/src/environments/environment.ts
@@ -9,9 +9,9 @@
 
 export const environment = {
   production: false,
-  mpsServer: 'http://localhost:3000',
-  rpsServer: 'http://localhost:8081',
-  vault: 'http://localhost/vault'
+  mpsServer: 'https://10.0.0.219/mps',
+  rpsServer: 'https://10.0.0.219/rps',
+  vault: 'https://10.0.0.219/vault'
 }
 
 /*

The tests will fail as they have 'localhost' hardcoded in some strings.

Expected behavior

Tests should succeed.

Additional context

This will fix the problem. Using 'URL' to extract the hostname should be different enough to component.formServerUrl() for the test to be worthwhile.

Start with src/app/shared/deactivate-device/deactivate-device.component.spec.ts and compare its hardcoded localhost expectations with src/environments/environment.ts. Run the tests using a remote RPS server configuration; done means the deactivation URL tests pass without assuming localhost.
